Details: St. Jude Children’s Research Hospital has taken the next step in its construction of a seven-story patient care and research tower at 315 Danny Thomas Place, next to the Chili’s Care Center.

The Crump Firm is serving as the project’s architect, with Evans Taylor Foster Childress doing part of the work. Flintco LLC is the project’s general contractor. All the design work is expected to be completed by September, and construction is slated to last about three years.
